I recorded this for an animated sequence I was doing that involved a bucket truck. I recorded a truck parked in a garage starting its motor, pulling out of the building, driving back into the building, stopping, hitting the air brakes and idling, backing up with backing beeps, idling again, and then honking its horn while pulling back out of the building. The truck circles the building again, pulls back in, hits the air brakes one more time and then cuts the motor.
